Title: Improvements in Acetylene Gas Generators.
Inventor: HADDAN REGINALD
Filed: 1900-06-16
Granted: 1900-08-11
Abstract: 10,994. Haddan, R., [Adams & Westlake Co.]. June 16. Acetylene.-Relates to acetylene generators of the type in which the supply of water to the carbide is controlled by the gas pressure. The apparatus, which is more particularly intended for railway-car service, comprises a number of generating-cells 15, combined so as to form a battery, and arranged so that they may be operated together or in succession as desired. The cells are mounted on movable supports 15<b>, capable of being raised and lowered by screws 47 for the purpose of renewing exhausted cells. Water is supplied from overhead tanks 19 through pipes 23, 24, and 27 to the connections 31 between the nipples 11, 12, 13, and 14 of the generating-cells and the gas-outlet pipes 35. By means of a valve 65 and a valved bye-pass 64, the head of water may be varied so that the pressure at which the water supply is automatically cut off may be different in the case of one generator from that of another. As the gas pressure is uniform throughout the whole system, the variable water head affords a means of automatically bringing into action one generating-cell on the exhaustion of another. In the base of each water-supply pipe 23 is a weighted lever, which only permits the back-flow of water when the pressure exceeds a certain limit. A safety escape valve is provided at 56<a>. To prevent the passage of water into the gas-distributing pipe, each of the gas-outlet pipes 35 is formed with an enlarged chamber 66 above the water tank ; this chamber is connected by a condensing-coil 49 with the distributing-pipe 41. In replacing an exhausted cell by a freshly-charged one, escape of gas is prevented by means which ensure the closing of the valves 54 and 76 in the nipples of the generating-cells and connections 31 between them and the gas-outlet pipes 35. According to one arrangement, the screw 47 is rendered inoperative by a pawl which is automatically thrown out of engagement with a ratchet-wheel when the valves are closed. Alternatively, the two valves are closed by springs on the removal of a detent engaging their controlling-arms.

Abstract: 22,608. Krummel, L. C. Dec. 11. Annular-chamber type.-A compound rotary engine, fitted with an automatic combined valve and abutment is shown in Figs. 1 and 3. The shaft 6 has cranks 7, 8 carrying rotatable ring pistons 11, which work in the cylinders 1. The rocking abutment 14 has a projection 33, which slides in a recess in the casing, the ends o f the recess being connected with the steam and exhaust passages 25, 26 respectively, so that the edge 24 of the abutment is pressed against the piston. A recess 19 in the abutment serves as an exhaust port. A double ported reversing-valve 27 controls the steam and exhaust passages, and, when rotated, the direction of flow of the steam is reversed, and the abutment automatically reverses. A cut-off valve 47 is actuated by a rocking shaft 52, connected to a cam 56 on the main shaft. A cut-off valve may be fitted on both sides of the engine. The exhaust steam from the high-pressure cylinder, after passing through the port 29 of the reversing-valve into the chamber 31, passes through the port 28<a> into the low-pressure cylinder. The engine may be used without compounding. In a modification, the abutment is non-automatic, and is held in its required position by means of a spring.

Granted: 1902-01-23
Abstract: 25,521. Scholl, A. Dec. 13. Compressing; exhausting.-Pumps for corrosive gases, in which liquid seals replace metallic valves, have the disadvantage that a high column of liquid is required to balance the difference of pressure between the suction pipe and pump, and pump and delivery pipe respectively. This is obviated by introducing a resistance to the flow of liquid between these parts. In Fig. 2, it takes the form of small pipes 10, 30 with a number of sharp bends between the suction pipe 23, the pump barrel 25, and the delivery pipe 27. In Fig. 3, the pipes branch into smaller ones of the same aggregate area, while, in Fig. 5. the pressure which wou)d be caused on the down-stroke of the piston a forcing liquid through the trap c into the suction pipe d is relieved by the downward movement of the liquid in the pump barrel inducing a current through the passage i.
